IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part ofrLetters Patent No. 162,899, dated May 4,1875; application filed March 15, 1875.

To all whom it may concern:

Be it known that we, C. F. CARR and STEPHEN S. WILGOX, of Adel, in thecounty of Dallas and in the State of Iowa, have invented certain new anduseful Improvements in Grain-Binders 5 and do hereby declare that thefollowing is a full, clear, and exact der lower portion of the bindingdevices( Fig. 6

is a section of the same upon line a' w of Fig. 5. Fig. 7 is anelevation of the inner sides of the devices employed for picking up andsevering the binding-cord. Figs. 8 and 9 are vertical sections of thesame upon line e z of Fig. 7, showing, respectively, the position of thejaws before and after they have grasped said cord. Fig. 10 is aperspective view of the fastening or tie employed for conlining the endsof the bindingcord.

Letters of like name and kind refer to like parts in each of thefigures.

The design of our invention is to render practicable the automaticbinding of grain by machinery; and it consists principally in the meansemployed for arresting the passage of grain to the machine during theoperation of binding a gavel, substantially as is hereinafter shown. Itconsists, further, in the means employed for passing the confining cordaround the grain, substantially as is hereinafter set forth. Itconsists, further, in the means employed for operating the pick-up jaws,sub! stantially as and for the purpose hereinafter shown and described.It consists, further, in the means employed for severingtheconiiningcord, substantially as and for the purpose hereinafterspecified. It consists, further, in the means employed for forming andsecuring the metal clip or clasp in place upon the binding-cord,substantially as and for the purpose hereinafter shown. lt consists,further, in the means employed for feeding the metal ribbon beneath theforming-dies, substantially as and for the purpose hereinafter setforth. It consists, further, in the means employed for removing thebound grain from the machine, substantially as is hereinafter shown anddescribed. It consists, further, in the means employed for limiting themotion of the pivoted binding arm, substantially as and for the purposehereinafter specilied.

In the annexed drawings, A represents the base of our machine,constructed preferably of metal, in the form shown, its central portionbeing provided with a transverse halfround cavity, A', while upon itsfront end is formed a table, A", that has substantially the same generalplane as said base, and is placed at a point below the upper edge ofsaid recess. To or upon the rear end of the base A is pivoted one end ofa lever, B, which has substantially the same length and general width assaid base, and is provided upon its lower side with a semicircularplate, B', that corresponds in shape and size to, and coincides with,the cavity A'. From the lower side and center, at each end of the plateB', projects downward a stud, C, that serves as a guide for, and uponwhich a curved plate, D, slides vertically, the lower ends of said studsbeing enlarged, so as to prevent said plate from becoinin g disengagedtherefrom. A spiral spring, c, is placed around each stud C, and,extendingl between the plates B' and D, press the latter downward to itsfarthest limit. The lever B is arranged to rise sufficiently to enablegrainstalks to pass between the forward lower edge of the plate D andthe correspondingedge of the cavity A', suitable guides E and E beingarranged above the table A" to snp port said grain while passing overthe same.

When a sufficient quantity of grain has passed into the holder A', bydepressing the outer end of the lever B the stalks of said grain will becompressed and caused to assume the form shown in Figs. 3 and 4, so asto enable them to be bound by the mechanism hereinafter described.

The lever B being arranged so as to move downward to the same point eachtime, the varyin g sizes of the gavels of grain would render uniformcompression impracticable were it not for the plate D, which is placedat such a distance below the plate B' as to bear upon the smallestgavel, while when larger gavels are received said plate D will yield asmuch as may be necessary for their accommodation. In order that theinward passage of grain may be arrested while each gavel is beingcompressed and bound, a shaft, F, is j ournaled within, and extendsbetween the guides E and E, and is provided with two or more teeth, fand j', that extend radially outward from one side. Aspring-arm, f',extends outward from the side of said shaft opposite' to said teeth, andis connected by means of a rod, g, with one end of a, spring-arm, G,that is attached at its opposite end to or upon a block, H, which latteris journaled upon the side of the base A. The inner end g' of thespring-arm G extends forward beyond the block H, and is looselyconnected with one end of a rod, I, that at its opposite end isr pivotedto or upon the lever B, the arrangement being such as to cause thedownward motion of said lever to move the spring-arm G rearward andupward, and thereby depress the outer end ofthe arm f', by which meansthe teeth f and f are raised to a vertical position (as shown in Fig. 4)whenever said lever has moved sufficiently. `When said lever is raisedsaid parts assume the positions shown in Figs. 2 and 3, said teeth beingturned downward below the line ofthe guides E and E. It is necessarythat the teeth f and f should be turned upward at the instant when thelever B has commenced its downward movement, and should remain in suchposition until said lever has nearly returned to its normal position,which result is accomplished, first, by so proportioning the relativelengths of the arms j', g, and G', as to render necessary but a slightmotion of said lever in order to move said teeth the required distance,and next, by causing the lower end of the rod I to slide freely downwardthrough said arm g', and attaching to the former a spiral spring, i,which, at its lower end, bears upon the latter. Vhen, now, the teeth fand j' have turned upward to the desired position they are arrested bysuitable stops, after which the operating-rod I will pass downwardthrough the arm g', and merely compress the spring c'. The grain, whencompressed, is bound by means of a cord, K, which passes from a spool orreel, L, beneath the table A", rearward through a stud, M, that extendsupward froln said table, through a slot, a', in the front wall ofthecavity A', beneath and around the grain, through a slot, d, in the frontwall of the spring-plate D, and thence to a pair of nippers, N, whichare pivoted to the lower side of lever B, and are held together by meansof a spring, a, as seen in Fig. 7. It is intended that the pinchers Nshall grasp the cord L just in rear of the stud M, and that they shallbe opened at the instant they reach the upper end of the latter, whichresultis accomplished by forming upon the rear side of said stud aA-shaped lug, m, that passes between and separates said pinchers as theymove downward. When the pinchers pass below the lug m they automaticallyclose together and grasp the cord L, which is just beneath. To removethe lug m from between the pinchers the stud M is secured to or upon oneend of a bar, m', which extends forward within a corresponding groove,a", and is capable of sliding longitudinally therein. A spiral spring,m", coiled around said bar, and arranged to bear against the front sideof the stud M, causes said parts to maintain position at the rear limitof their motion (as seen in Fig. 8) until the instant when the pinchersN pass below thc lug m, when the outer hooked end of said bar m' isengaged by a wedge-shaped incline` O, that is formed upon the side of abar, O', secured to and extending downward from the outer end of thelever B, and is by said incline moved outward to the position shown inFig. 9.

After the grain has passed into the holder, the end of the cord L, whichis held within the pinchers N, is carried downward until it bears uponthe upper side of the table A", beside the cord which has just beendrawn through the stud M, at which instant both portions of the saidcord are severed, by means of a cutter, I), that is attached to thelever B, just in rear of said pinchers. The severed ends of the cord Lare fastened together by means of a sheet-metal clasp, Q, which isformed upon and cut from the end of a strip of metal, Q', in thefollowing described manner: 'lhe strip Q' passes from a reel, It, placedbeneath the table A", between two geared feed-rollers, S and S', thatare suitably journaled at the edge of said table in such position as tobring the periphery of said lower roller S' just above the upper surfaceof the latter. From the feed-rollers S and S' the metal strip passesbeneath the cord L, across the rear side of the table A", toia'pointjust beyond the transverse center of the same, where a curved lug, T,(seen in Fig. 1,) turns its end upward and backward over the ends ofsaid cord, when a die, U, attached to and moving with the lever B,impinges upon said metal, presses its backward-turned end upon saidcord, and, at the same instant, a cutter, V, placed at the side of saiddie, severs the clasp Q from the strip Q'. In order that the clasp Q maybe more rmly fastened together, the die U is provided with twoprojections, u u, 85e., which pass into corresponding cavities u' u',Ste., in the table A", and, cutting through the clasp Q, press downwardupon one side of the cord ends two lips q and q, as seen in Fig. 10. Themetal strip Q' is fed forward, just before the lever B reaches the limitof its downward stroke, by means of a series of ratchet-teeth, o', o',&c., which are formed upon the side of' the bar O, opposite to theincline o, and engage with a toothed wheel, S," that is secured to orupon the end of the shaft s of the lower feedroller S'. In order thatsaid bar O may be relieved from engagement with said wheel S" upon itsupward movement it is pivoted at its upper end and is held in positionby means of a spring, o", which yields readily when the inclination ofsaid teeth o' ando' tend to press said bar away from said wheel. As soonas the bound sheaf is released from pressure by the upward motion of thelever B, it is thrown endwise from the holder A' by means ot' a barbedstud, W, that projects from and works within a slot formed within therear lower side of said holder. The stud W is attached to one end of abar, W', the opposite end of which projects beyond the side of the baseA, and is hooked, as seen in Fig. l-. A bar, X, having a wedge-shapedlower end, w, is pivoted to the rear portion of the lever B, in suchposition as to cause said lower end to engage with the hook w of the barW', as said lever moves downward, and, by means of its inclined outeredge, move said hooks, said bar W', and the barbed stud outward. Afterpassing nearly to the downward limit of its stroke, the bar X isreleased from engagement with the bar Il" by cutting away enough of itsface to enable the hook w to slip ot't' from the same, after which saidbar W' is returned to position (as soon as the bundle of grain isloosened) by means of a suitable spring. The upward movement of thelever B is limited and regulated by means of a screw, Y, which passesdownward through its end in rear of its lpivotal bearings, and bearsupon the base A. By turning said screw downward its end will come intocontact with said base and arrest the upward motion of said lever soonerthan when withdrawn by being turned in an opposite direction, by whichmeans the vertical dimensions of the opening through which grain passesto the binder are varied at will.

Having thus fully set forth the nature and merits ot' our invention,what we claim as new 1s- 1. The jonrnaled shaft F provided with thefingers j' and j' and spring-arm f', the rod g,

the spring-arms Gr and g', the pivoted bloclr H, the rod I, and thespring i, all constructed and combined to operate in the manner and forthe purpose substantially as shown.

2. The pivoted lever B, provided near its outer end with the pick-upjaws N, in combination with the perforated stud M m workin g within thetable A", substantially as and for the purpose set forth.

3. In combination with the table A" the cutter P attached to the lever Bin rear of the pick-up jaws N, and arranged to sever the binding-cord Ljust before the same is grasped by said jaws, substantially as is shownand described.

' 4. In combination with the die U, provided with the projections a andu, and secured to and moving with the lever B, the table A" havin g thecurved lugT andthe recesses a' and a' for the reception of saidprojections, substantially as and for the purpose specified.

5. 'The geared feed-rollers S and S and toothed wheel S", in combinationwith the ratchet-bar o o, attached to and moving vertically with the endot' the pivoted arm B, substantially as and for the purpose shown.

6. The toothed stud WV, attached to and moving horizontally with the barW', in oombination with the bar X, provided with the wed ge-shaped lowerend x, pivoted to the lever B and arranged to engage with the hooked endx of said bar X, substantially as and for the purpose shown anddescribed.

7 In combination with the pivoted binding or compressing arm B the screwY, passing downward upon its rear end and bearing at its lower end uponthe base A, for regulating the opening through which grain flows to thebinder, substantially as and for the purpose specified.

In testimony that we claim the foregoing we have hereunto set our handsthis 19th day of January, 1875.
